Building-integrated photovoltaics

Definition

Building-integrated photovoltaics (BIPV) are systems that integrate solar energy technology directly into the building structure, such as rooftops, facades, and windows. These systems not only generate electricity but also serve as functional building materials, contributing to both aesthetic appeal and energy efficiency. BIPV represents a crucial advancement in sustainable architecture, promoting renewable energy use while minimizing visual impact on urban landscapes.
